SOAP-PRESS.

SPECIFICATION forming part of Letters Patent No. 662,356, dated November 20, 1900.

Application filed September 11,1899. Serial No. 730,104. (Nomodel.)

fo (/,ZZ whom it may G01/warn:

Be it known that I, ENos J. FORRESTER, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Soap-Pressing Machines, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to soap-pressing ma- 1o chines; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

One object of this invention is to construct a machine provided with an endless carrier,

on which are placed by hand cakes of soap to be delivered in communication with the operated feeding mechanism and to be pressed in a mold and be delivered therefrom by an operating mechanism and again conveyed zo upon the endless carrier to be carriedto a wrapping-table.

Another object is that the various operating mechanisms are all operated by the drivingshaft and are arranged to alternately operate at a proper time for delivering a cake of soap through a channel before reaching the wrapping-table.

Figure 1 is a side elevation of my complete invention,s`nowing part of the Wrapping-table 3o broken away. Fig. 2 is a perspective view of a portion of the device for feeding a cake of soap in front of the mold and supporting an adjustable stop made use of in carrying out my invention. Fig. 3 is a detail side elevation of the cam located on the drive-shaft for operating the feeding mechanism. Fig. 4 is a top plan View of the same. Fig. 5 is a top plan View of my complete invention, showing a portion of the wrapping-table on which the 4o soap is to be delivered for wrapping. Fig. 6 is a detail side elevation, with a part broken away, of one of the rams made use of, showing its operating connection. Fig. 7 is aside elevation of the other ram, with a part broken away, showing its operatingconnection. Fig. S is a front elevation of the journal-frame in which the ram is supported and guided. Fig. 9 is a perspective view of a mold and the guide-plate in which the soap is to be pressed.

5o Fig. 10 is a detail side elevation, with parts in section, of the delivery mechanism for delivering the soap from the mold to the endless carrier operated by the driving-shaft. Fig. ll is a detail side elevation, with part in section, showing the feeding-operating mechanism operated by the drive-shaft. Fig. 12 is a detail front elevation of the sprocketwheel mounted on the driving-shaft, showing the manner in which it operates the mechanism for releasing the cake of soap from the 6o end of the die.

In the construction of the device, as shown, I provide a table l, mounted upon suitable legs or standards 2, to which are secured cross-frames 3, one located on each side and arranged for supporting the operating mechanism. In the center of the frame 3 and held in bearings is a driving-shaft 4, which is of such length as to project on each side of said frame and is arranged to carry a tight 7o and loose pulley 5. Upon the shaft t, between the frames 3, are mounted eccentrics 6 and '7, each of which is provided on its outer surface with corresponding grooves 3. The end 9 of the driving-shaft 4 is supported in a 75 bearing 10, mounted upon the floor for the purpose to rigidly support said shaft, preventing the same from vibrating while being operated by the belt 11. Upon the shaft 4 adjacent the pulleys 5 is a cam 12, held upon 8o said shaft by a set-screw 13. This cam is provided with a groove 14, so arranged as to operate a lever l5 in a reciprocatory manner by means of a roller 16, pivotally mounted upon said lever 15 and operating in said 85 groove 14 while said cam is in its rotary action. The lever 15 is fulcrumed at its center to a brace 17, rigidly mounted on the vertical member of the frame 3. The upper end of the lever 15 is held by means of a bolt to an 9o "arm 1S, one end 19 of which is secured to a detent 20, formed on a collar 2l, which is mounted upon the shaft 22, loosely mounted in a bracket 23, secured to the side of the table by means of bolts or lag-screws 24. On the end of the shaft 22, which projects through one bearing 25 of the bracket 23, is

mounted a disk 26, having a rubber bumper 27 secured to its rear surface, which is designed to come in contact with the frontend :too`

of the bearing 25 when said shaft 22 is brought to its limit on its outward stroke. Upon the top of the bearing 25 is provided a post 28, on which is fulcrumed a lever 29, having its inner end provided with a plate 30, which is for the purpose of coming in contact with the top of the cake of soap, pressing the same from the end of the die as itis conveyed from the mold. The end 3l of said lever 29 is provided with an eye 32, through which is passed a rod 33, extending downwardly and secured to an ear 34, formed on a right-angular arm 35. The arm 35 is pivotally mounted on a stud 36, securely held to the frame 3.

Upon the rod 33, a short distance above the ear 34, is a collar 37, between which is placed a spring 38, which is for the purpose of allo wing the rod 33 to pass downwardly through the ear 34 in case a strain should be placed upon the arm. 35 or plate 30 and will allow the same to assume its normal position when the strain is released.

The end 39 of the arm 35 is extended downwardly and brought into Communication with the hub 40 of the sprocket-wheel 41, which is securely mounted upon the driving-shaft 4 adjacent the cam l2. (See Fig. 10.)

The arm 35 is operated by means of a setscrew 42, carried by the hub 40, coming in contact with the end 39 of said arm,.(see Fig. 12,)which will cause the same to be oscillated.

Mounted on top of the table l a 'suitable distance apart are journal-frames 43, in which are adapted to operate and be guided rams 44 and 45, the inner ends of which carry a die 46, which is constructed of the same shape as the inner surface of the mold 47, located about the center of the table and supported by adjusting-screws 48, mounted in uprights 49 and 50, one of which is located on each side of said mold. The rams 44 and 45 are each provided with a keyway 5l, which is for-the purpose to keep said rams in a vertical position, preventing the same from turning, and this is done by means of a key 52, formed in the cover 53 of the journal-frame. (See Fig. 8.) A portion of the outer end of the ram is of a smaller diameter than its remaining portion and on which are provided screw-threads 54, upon which are placed nuts 55, (see Fig. 7,)

' which are for the purpose of adjusting the horizontal movement of said ram. On said Vportion between the nuts is placed a collar provided with ears 58, the upper ones of which,4

as before stated, are placed over the lugs 56 and the ones 59 are placed over the upper end 60 of an operating-arm 61. Between the collar 55a and the inner nut 55 I place a spiral spring 62. This is for the purpose while the rain and arm 6I are in their horizontal movement for the spring to allow the arm 37, carried by the arm 6l, to operate during 'its stroke in case strain should/be caused by the action of pressing the soap in the mold 47. The end of the ram 44 is also provided with a portion of'smaller diameter than the ram proper and on which are also formed screw-threads and nuts 62'. Between the nuts 62 I place a collar and an arm 63, which is of the same construction as the one previously described, and i is also carried by an operating-arm 64. The construction of both rams is the same,with the exception that the ram 45 is provided with a spring, while the ram 44 is not. It is only necessary to use the spring 62 as described on but one of the rams, as the ram to which it is applied has the essential function to perform. The arms 6I and 64 are pivotally mounted at their lower ends upon the shaft 65, mounted in any desirable manner within the frame 3. (See Fig. l.) Each of said arms is provided with a curved arm 66, which extends inwardly and communicates with the eccentrics 6 and 7. On the end of said arm 66 is provided a roller 67, which is held thereon in any desirable manner and is constructed to operate in the groove 8,formed in said eccentric,as shown in Fig. l0. By this construction as the eccentrics are revolved the movement of the roller within the groove 8 will operate the arm 66, causing the vertically-operating arms 6l and 64 to oscillate through a slot 68, formed in the table l. (See'Fig. 5.) Upon the end 69 of the shaft 4 I place a hand-wheel 70, which is for the purpose of rotating said shaft by hand before the belt is shifted upon the tight pulley when it is desired to place the machine in a certain position before operating. This is sometimes necessary in case some obstruction should be lodged within the operating parts of the mechanism mounted upon the top of the table. Upon said shaft,adjacent the handwheel 70, is mounted a cam 7l, which is of the same construction as the cam l2, previously described, but is located differently upon said shaft,` and is also provided with a groove 72, by which a lever 73 is operated by means of a roller formed upon the lower end of said lever 73 and designed to lit within the groove 72 of the cam. The lever 73 is fulcrumed near its center to a brace 74, which is rigidly mounted on the vertical member of the frame 3, (see Fig. 11,) and its upper'end is pivoled to a hori- Zontal arm 75, having its outer end 76 held by means of a bolt to the arm 77, securely held to a shaft 78, forming parl of a ram 79. The ram 79 is guided in a bearing 80, the horizontal portion of which is secured to the under side of the table in any desirable manner and is provided on its lowersurface with projecting lugs 8l, in which are provided slots 82. Upon these lugs 8l l place a stop 83, consisting of a bent strip 84, provided in its vertical portion with two rods or pipes 85, securely held to a vertical portion by nuts or any other means, and its ends 86 are free, yet brought in close contact with the tube 87, mounted upon theend of the horizontal portion of the strip 84. The stop is adjustably secured upon the lugs 8l by means of a bolt passing therethrough and through the slot 82, and when the same is adjusted to any desirable location the bolts are tightened and the same will remain in a IOC IIO

rigid position. Upon the tube 87 (see Figs. 1

and 2) is supported a rubber tube 88, which is passed upwardly and secured to a faucet S9, formed in a water-receptacle 90, which is 5 mounted upon a riser 91, held in any desirable manner to the top of the table l. The

object of the stop 83 is for the purpose of allowing the ram 79 to at all times come in contact with the center of the cake of soap, so as to 1o convey said cake in direct alinement upon the guide-plate 92, mounted in front of the mold 47. The guide-plate 92, as will be seen in Fig.-

9, has one end bent upwardly to correspond with the curve of said mold and is provided at its bottom with a threaded stem 93, which is passed through an aperture formed in the table for the purpose of adjusting said plate to any desirable height to correspond with the inner surface of the mold.

To the side 94 of the table 1 I support, by means of brackets or like devices, a trough 95, having vertically-projecting sides 96. The trough 95 extends longitudinally from the upright 50 and projects a short distance beyond the end of said table. The opposite end of the table 1 is provided with a bearing 97, in which is supported a shaft 9S, having on one end a sprocket-wheel 99, over which is passed a sprocket-chain 100, communicating with the 3o sprocket-wheel4l, mounted upon the drivingshaft. \Upon the opposite end of the shaft 98 l provide a roller 101, over whichis adapted to operate an endless belt 102, which extends longitudinally the entire length of the table and passes over and under a wrapping-table 103, which is located in alinement with the trough 95 and is for the purpose to receive the cakes of soap after the same have been delivered from the machine.

The table 1 is provided with a guide-strip 104, provided on its end with a tube 105, which corresponds with the tube 87, formed on the stop and on which is mounted a rubber tube 106, passing upwardly and also secured to the faucet 89 of the water-receptacle 90. This is for the purpose of supplying water to the guide-plate 92, a passage-way 107 being formed between the tubes 87 and 105, through which the soap is adapted to pass.

The operation is as follows: The soap is brought upon suitable racks in communication with the machine, and the operator places each cake upon the endless carrier 102 at a distance of about six or eight inches apart, as shown bydotted linesin Fig. 5. The

endless beltis conveyed by the sprocket-chain 100, operated by the sprocket wheel 41, mounted upon the drive-shaft and operating the sprocket-wheel 99, formed on the shaft 9S. 6o When one of the cakes of soap is in alinement with the passage 107 and directly in front of the ram 79, the action of the cam 71 at that moment causes the ram 79 to be eX- tended forwardly by the movement of the lever 73, bringing the cake of soap upon the guide-plate 92 in direct alinement with the inner opening of the mold 47. When the cake of soap is in this position, the ram 45 is brought forward by means of the operating-arm (i1, which action is performed by the movement of the segment 7, rotated by the driving-shaft 4, bringing the die 46 in communication with the cake of soap, pressing it within the die 47, while at the same time the die 46 of the ram 44 is brought into communication with said soap within the mold by the action of the arm 64, operating by the cam 6. The arrangementof the cams upon the driving-shaft 4 is such that when the arms are in this position the ram 45 will be allowed to press the cake of soap after the same has been pressed by both dies through the mold 47, while at the same time allowing the ram 44 to assume its normal position. This action by the operation of the sprocket-wheel 41 brings the set-screw 42, mounted on its hub, in communication with the lever 39, pressing upwardly on the rod 33, causing the lever 29 to bring the plate 30 in contact with the top of the cake of soap, releasing it from the die. At the time the cake has been released from the end of the die the disk 25 upon the shaft 22 is brought forward by the action of the lever l5, operated by the cam 12, conveying the cake of soap over the plate 10S onto the endless carrier at the point indicated by the letter a and is conveyed by the endless carrier to the wrapping-table 103, where the same is removed from said belt and wrapped.

The cams 12 and 7l are so arranged upon the driving-shaft as to operate each of the mechanisms at a given time and so as not to in any way coniiict with the action of the rams 44 and 45, as the same are brought back into their normal position before the rams are brought forward for pressing the cake of soap.

I may, if desired, place upon the rams 44 and 45 any shape of die, which in this case the mold will necessarily have to be arranged to correspond with the shape of the die, and this I do by removing the mold 47 by the use of the set-screw 48, and any mold may be placed therein and held rigidly when said setscrews are adjusted.
